hi i have a problem with my gtalk account. i've deleted and created it again still it doesn't work. it simply doesnt work on 3G but when on WiFi it works smoothly.

even gmail works well on WiFi but not on 3G. this problem is restricted to only 1 gmail account of mine. another 3 accounts dont have this issue. for gtalk too only this account has the problem.

can someone help me with this. i read somewhere that it might be gmail locking my account to my first sim something that is done in android but i don't get why it doesnt occur to the other accounts.
