... Although a jailbroken 3G might be used with an adapter card riding piggyback on your SIM card, thus rendering a "true" Unlock obsolete. Don't know nothing about Indian carriers in this respect, though.
Okie so when my phone has cydia it means it is unlocked or jailbroken?
my phone is 2G... so please give me a solution..... can i unlock it again?
Can it be a problem related to sim bandwith... because it was working in UK but not accepting in India?
Actually my friend who iPhone for me is also having an iPhone from UK unloked with ziPhone... and his handset is working in India..... actually his handset do have Cydia installed..... so what is the difference between his handset and my handset?
