I hv an ip4 sing unit got from apple store and another ip4 unit fr maxis.the Sing unit is upgraded to OS 4.1,n d maxis is still OS4.02.few problems my my observation.

Both unit: sometime try to auto send SMS.why ar?

Sing unit:even after OS upgrade to 4.1,still xperience drop calls,accidentally mute/call others due to proximity sensor issue.funny if call than put yr palm over d sensor working fine.
The safari also xperience hang when u try click the open new page button,then hv to resort to close d program from double tap homescreen.only then safari turn normal.

Maxis unit:no specific prob yet,just 1 day old

Hey guys,uve use maxis Ip4 n I've been hit the overheat warning.this happen when I play angrybirds and I pause the game n click d power button as someone come n talk to me.after 3-5 min,when I on my phone shows the overheating sign. Then wait to cool off.
