Hi, I have iPhone 4 jailbroken, couple of days ago its skype was working, but after some time it stoped working, when ever I tried to update it from my handset it gives a popup with message to update iOS 4.3, I just want to know that how can I run my skype without updating iOS. there are some other applications which were working few days ago but know they are working. is this cause of jailbroken or due to some other reason. please guide me.

Thanks,
Safdar
