1, whr to buy--its up to u..u can get it frm maxis, but it wud take ages...u can get it frm handphone shops but make sure the r selling the real ting...beware of fakes...and u hv the option 2 visit the garage sale n check who is selling..
2. thr wud be warranty, but dun reply too much on tat coz they always end up saying 'oh soorry sir, we dun cover tat in da warranty'
3. for sm ppl here, iphone has become part of their life whr they cant seem 2 move abt without it...its case 2 case basis bro...totally a personal choice
no matter who ur phone is frm, u can jb..no worries abt that...
but like u said, maxis wud nt entertain a jb set, so if u can, restore da device if u can b4 sending it thr...
on a slightly similar note, i was told by my bro tat he was 100% sure he heard a maxis staff explaining 2 a customer a certain way to get illegal apps on their phones....
i wonder how was he gonna do tat w/o jb...
