the missing functions of this device are actually quite irritating and disappointing, for example we can't send our contact through sms right, or maybe there is a way that i didn't find out...same basic functions like i mentioned no custom ringtone and the volume which even a normal phone can make it...i can't comment much about the apps coz it's a new os, i believe there will be more apps developed as time goes by...what i am trying to say is, this device doesn't worth it's price, i won't make any complaints if it was cheaper... if you were to spend this much i'd suggest you to go for iphone4 which is actually slightly cheaper and much better...but nothing i can do though, since i've bought it, i'll expect something impressive on the upgrade next year...

help!!! my phone ran out of battery for a few days already and i just got it charged, but there is an error says my sim card is invalid, what can i do???

omg, i just realized that i took the sim card out and placed it in the wrong way, hahaha ><
