I have been using unlocked iPHONE 3G on T-Mobile network from past 2 years.
When I checked my Network =>About here is the info:
Version: 3.1.3 ( 7E18)
Carrier: Carrier 5.1
Model: MB048LL
Now sometimes when I try to go to iTUNES and download some free apps and install them, they give
me an error saying needed iOS 4.
Questions:
========
1) Can I upgrade my phone to iOS4 or newer if there is anything available ?
2) Will there be any advantage on my iPHONE (tmobile) if upgrade to a newer version compared
to the one I have ?
3) If YES how can I upgrade the OS on my iPHONE ?
4) After the upgrade will it still work with my T-Mobile network ?
