IPhone :: How Does The 4s Calculate Altitude
Mar 12, 2012There's a few apps out there that can work out altitude - better seemingly than an altitude watch.
It's obviously using GPS but how and how accurate is it?

Me: When is my next meeting
Siri: Your next meeting is at 6:36 tomorrow
Me: Wake me up one hour before my next meeting
Siri: It's set for 10:50 pm
actually she set the alarm 1 hour, right after the movement when i asked her to set the alarm, this makes no senes

Since there is no way to bypass a sensor for indoor spin class, I had to set my MA to stairstepper. I chose SS over Eliptical because I assume that the MA device would look for foot movement (to calculate calories) instead of arm movement (because the notes specifically say not to grip the stationary handles on the eliptical). Anyhow, I completed a 60+ minute spin class at vigorous effort for at least half and had an average heart rate around 75% and it said I only burned 300 calories. I know that 1 hr of spin burns close to 600 calories..does the MA device take into consideration the type of exercise chosen (e.g. stair stepper) and uses that activity blended with HR and motion to calculate the calories burned? If that is the case, then MOTO needs to do two things: 1) allow users to bypass sensors for exercise so they can still capture the proper exercise and not a "general" one and 2) create a "general" one for quick start options if someone doesn't care to record the activity type. It all depends on how calories burned are calculated.In the meantime, which activity should I use for Spin class....if the hands don't move, I would think that eliptical is not a good choice. What about running or walking...does that use arm movement also? Overall, would love a little more info on how the measurements are calculated.

The Long/Lat is ok but the altitude is way out, I was by the beach a meter or so above sea level and was getting a reading of 50 meters.
I'm looking for a suitable Motorola handset with GPS to deploy on a high altitude photography experiment.It needs to be able to send a regular stream of sms with GPS coordinates. This part may require an app or modding of some kind.It needs to operate on UMTS850Mhz.Can anyone think of a handset that would be suitable?
View 1 Replies View RelatedI'm evaluating if Motoactv will be suitable for my needs as minimizing weight carried is a big concern.Will be going upto 16k feet - So I wont have access to a computer for 25-30 days to move the data to the website etc. the unit will be powered off only at night.My aim is to track at minimum heart rate, pedometer, altitude, route mapping, temperature.
Q1 - Assuming I can supply the actv enough power via solar chargers etc. Will it be able to store all the tracked data for such a long period?
Q2 - I can also carry a tablet - I also need advice on if its possible to move data from the actv via usb to the tablet ( assume zero internet connectivity )

Now this is speaking from a DEVELOPER point of view. Would you like to see iPhone exclusivity stop? To me, yes, obviously, because this means the App Store can be in more hands, and my apps can have a MUCH larger audience. Yes I know there is a lot of market share already, but look at VZW, T-Mob etc and if we got their eyes on our apps. you should be able to fill in the rest. What do you think from a developer point of view?

View 4 Replies View RelatedSo, I am based in UK and managed to "Reserve and collect" a 32gb iPhone 4g. However, on my confirmation e-mail, at the bottom, it says:
Pre-authorization does not guarantee iPhone availability at an Apple Retail Store. iPhone is sold on a first-come, first-served basis. Your reservation is valid for pick-up only at the Apple Retail Store that you selected. If you do not collect your selected item on the specified date, your reservation will be cancelled and the item will be returned to stock.
My dilema is it's going to take me 2+ hours and lots of expense to get to the store on the 24th, the last thing I want to do is turn up at lunch time (about when i'd finally arrive) to find out they've sold mine / sold out.
what does it mean when itunes says " This iphone cannot be used because the Apple mobile device service is not started?

We have purchased SSL Certificates from verisign to do 802.1x authentication. However when attempting to connect I still receive the "Not Trusted" Certificate message. In testing I have e-mailed all of the seperate certs to myself to see for sure which one in the chain is not trusted. I find that the Root Certificate "Verisign Class 3 Public Primary Certification Authority - G5" dated 11/7/2006 to 7/16/2036 is the one that mis matches the one in on my phone. I read that the key for the cert http://support.apple.com/kb/HT5012 doesnt match the one directly from Verisign therefore verisign cert isnt trusted.

With my iPhone 4, running iOS 5.1.1, syncing notes in Mail results in a stange blank Notes document appearing in the Notes sidebar in Mail. The Notes look like a yellow sheet of ruled paper, as they do on my iPhone, but they open to reveal no information other than their names.
Once opened, they disappear from my list of Notes, and upon the next sync via USB cable from my iPhone to my Mac, the notes also disapepar from the phone. When opened in Mail, the blank and useless no-longer-a-note Notes will not close unles I quit Mail. I am running Snow Leopard 10.6.8. In Mail, I've tried both listing the Notes in the Inbox, and as their own separate group.

I only have 800 MB free (in Settings -> General -> About) but iTunes tells me I have 3.9 GB. If i remove the phone and then reconnect, iTunes will then show me 800 MB (0.8 GB) I just reproduced the problem by simply going into the apps tab and moving an app to a different folder. My free space immediately changes from 0.8 GB to 3.9 GB. What's going on ?
