actually maxis can't even blocked the phone. Cuz Maxis only has a authorized on SIM card and can blocked the sim card only...not the phone. My friends using maxis iphone for 1 month then not pay the bills and guess what, maxis blocked only the sim and not the phone. If you jailbreak your iphone, even it is from maxis you will get no signal after all. you need to use an ultrasn0w for unlock it unless your phone is official unlock from apple™ it self.

using dif firmwares dif phone country. and no problem at all. Malaysian Sucks...thats the fact. btw unlock using ultrasn0w instead of yellowsn0w.

but maxis iphone cant use DiGi and Celcom line right? or im wrong?. I dont know if other maxis user can use other sim card on it (without hailbreak or unlock).
