My iPhone 2g 8g has developed a problem.
Vibrate no longer works (button switch on)
New Voicemail, new mail, sent mail, calender alert, lock sound & keyboard cliks sound not work. The phone will ring on incoming calls. This happened after I installed winterboard, but I have since removed it and its the same. Any ideas???

If this just occurred, then it seems as though it is a software issue not hardware.
Try doing a hard reset by holding both the home and power buttons and letting it reboot. If that doesn't work.
My suggestion would be that you do a restore and re-jailbreak and see if that will cure the problem.
Make sure you set it up as a new phone, to avoid any corrupted file that may be there.
Sorry to hear your having a problem, good luck.
