I got my iPhone from USA,and have successfully JB to FW3.0. Before this, i'm on FW2.2 and i can't connect to the internet using my 3G connection (i'm using MAXIS). so decided to upgrade to FW3.01. right after i've upgrade it, i can use my 3G already. can check email, surf the web, etc. no other apps were installed. neither appstore nor cydia.

after a week or so, i already have a few apps installed from cydia and appstore (free apps). then, i tried to use my 3G again. to my shock, the problems occured again. i can't use my 3G. i've already bring my set to MAXIS centre. they said it's because of the apps.

any ideas?

Problem solved! I reset my network settings n restart my iphone.source of problem,not so sure.might be caused by syncing.

i believe theres a thread discussing about ur prob.and i managed to solve it before.but,i forgot already n was about to ask the same thing also.really glad if someone could give a hand.
