Nokia :: 5530 Browser Closes On Its Own - Shortcut Icons Disappear From Home Screen

I have a nokia 5530 xpress music mobile - (Christmas present) and was wondering when any new firmware is going to be released; The native browser just closes on its own (sometimes active sometimes inactive) The phone is a little slow loading up and menus (know this may be down to apps etc and memory card) The shortcut icons disappear sometimes from the homescreen (causing a reset to rectify) and when I change them the shortcut on the far right changes itself back to facebook The phone sometimes gets stuck on a white screen at startup which can only be solved by removing the memory card and starting up then reinserting There are a few more minor things but they don't really matter but I have noticed the touchscreen can be quite unresponsive needing quite firm touches or repetitive touches (yes I know some things require double touch) I was also wondering why my phone keeps disconnecting from the wifi source (I have a standard home router) - I know some routes 'refresh' themselves however I don't have problems with my computers or laptops (yes I know its different hardware) Done get me wrong its a good phone, with great features and I am not complaining however I just expected less obvious faults not ones that can cause disruption in normal day-to-day use URL...
