Sony Ericsson :: Aspen And Gmail IMAP

I bought the SE Aspen couple of days ago and ran into an email problem. Im located in Finland and using Sonera's network (all bells and whistles installed). The Ready to Run app loaded all settings ok and browsing via exploder is ok. SMS and MMS are also working as they should. But for some reason when im trying to access my gmail IMAP account via Aspens email app I get a sync error -message when in 3g/gprs areas. In wifi the folders + inbox load ok (allthough the folders appear to be empty). In my previous devices i've used ProfiMail (which I think is THE mobile email app if you're using IMAP) and I installed it to Aspen too. Same thing here, in wifi everything works (every folders content in displayed properly) but when out of wifi area > sync error.
I've tried to play with the settings (have also set them manually as service provider's web manual instructs) and I'm pretty sure Sonera's settings are ok, since browsing, SMS and MMS work when in 3g/gprs coverage. access my gmail account via exploder also in 3g/gprs so im able to read incoming mail but because of my work (sales) i rely heavily on the information i have stored in my various gmail folders when on the road > accessing these and manipulating them via browser isnt fun/ possible.Also one other "fault" I have discovered in Aspen is that when using network updated time zone, it suggests that i change my time zone few times in a day (im in +2 zone and Aspen tells me to switch to and from +3 zone every now and then). I never had this problem with my previous (non-SE phones).
