Dear folks,
I purchased this unlocked and jail-broken iPhone 3G on eBay. All I have to do is insert my SIM card and use it, so I do not really understand how to unlock and jail-break this brick.
When I checked the Cydia account, a whole bunch of apps were reinstalled by previous owner. I try to delete some of them to boost the phone. My major concern is:
Are there some apps that I can not delete? or the phone wii be locked again?
Instead of deleting apps manually, is there a better way to do so?
btw: my OS version is 3.1.2.
Thank you so much!
