I recently changed my cellphone (BB to Motorola Defy) with T-Mobile services.

I am able to browse, open youtube, web pages etc...but when I click on Gmail icon, i get a error message " The application Google apps(process
com.google.android.googleapps) had stopped unexpectedly. Please try
again" It asks us to force close.. I am unable to open GMail, Market etc, anything related to google apps....

i dont know what to do....PLEASE HELP!

P.S: I did not get this defy from T-Mobile..but from a friend...so cant go to any t-mobile shop to get it rectified....please help
