Then you are not sure what you are talking about. When I explain my necessity to have push mail and its indispensable for the line of job I am in. Which means I take my emails seriously and my device is hooked to a data plan for the mails to be pushed to my phone the moment it arrives to my gmail inbox.

So much of your wifi and within less a minute your emails comes in 

So much of all your A's scored in your A levels when simple task/requirement cannot be replenished with a good input. 

Ill try thebyani after this. Really trauma now to try ICS. Most of time on the move n push mail not coming in means trouble in where work matters.
I doubt it works. I was on stock wanam also tried wanamlite 9.5 and 9.6. Doesn't work well at all. Mails don't come in unless I manually refresh and wait. However ill give the thebyani a try. Main concern is email comes in when I'm on data connection.

The shop isn't doing anything for you.

Enter recovery mode and wipe phone, once wipe your phone will be clean but password unlocked.

dont throw la. use odin flash stock firmware.
good as new.

hmm if enter recovery when wipe wont ask for unlock password ah? if like that whats the point of putting password 

If all else fails, use Odin to flash a Stock Rom again....everything start from scratch....no need to throw phone away....
