My OTB 1.1.2 Jailbroken Initially worked fine till Erasing All Contacts... Help....:

All features were working fine including Phone as using a Turbosim card until after I erased my contact list...

Now Not able to Surf on Safari, ie. with Installer, also not able to Update.
Noticed that the programmes I have installed inthe iphone areal not reflected in the 'Uninstall list' in Installer too.

Another problem is in 'ITunes' not able to access.

Wifi is working fine and logged on and able to check emails,update weather etc.. (i.e Internet connected)

SO now very confused when went wrong.... Appreciate if someone familiar withthis problem can assist.
