thx bro anyway.. will try to figure out other option b4 i restore it

but taking out the sim card would be more difficult than reboot right? Or u mean the problem solved by using ur method?

let say i wanna restore back.. but still my iTunes alr backup all my apps and setting everytime when i sync apps right?
so now i juz restore my phone, then jail break and click sync all the apps into my iphone again? correct?

ok bro... thx for ur info...

bro.. another question, wat bout those apps u had previous installed via cydia? u hv to re-install back all over again? another way to back up it?

looks like i'm not the only one who experienced this.. even my friend had encountered this problem too.. well we suspect is it the phone prob? transmitter receiver weak?

i knew this problem had been discussed somewhere but i cant find the thread, so i decided to post here and if anyone can guide to the relevant post.

recently my phone keep appearing " Could not activate cellular data network" when i online, i did reset the networking setting but the problem still occur.. so wat is the solution?

iPhone Generation :3GS

i id restart and reset networking setting like hundred times and the problem still occur. Well it turn back to normal the next morning, well i can only assume that maxis line down at that period, maybe?

having problem to connect my pc to iphone using winscp.. it keep pop out "server unexpectedly closed the network connection" before that was working fine until i had changed the root password due the the iKee issues.
Then since after that i couldn't connect it using winscp, but i pretty sure that i still rmb the password cos i had try log in using mobile terminal n it works... so any sifus can help me on this?

restart for hundred times alr still problem occur, what bout username? still put "root"?
