Data (GPRS) Connection Issues

I just hooked up my Galaxy S.  I was supplied a work phone here in Thailand, but I didnt want to carry 2 phones, so I had them put a unlimited GPRS package on the account and put the Sim card into the SGS.  I did this on Tuesday.

Yesterday I started to play around with the phone, seem to work awesome.  I added my 3 email accounts to the phone, 1 Gmail, 1 Hotmail (Pop3) and 1 Business (Exchange).  The internet worked fine, apps worked fine and the updates seemed to work fine as well.

This morning (1 day later) I had connection issues.  The exchange email would not connect to server, gmail would not connect either, internet give server connection fail and apps and updates do not work.  However, hotmail still works fine.

So Im looking for suggestions on where to trouble shoot.  I have tried looking thru menus and seeign if I checked something off I should not have. 

At first I was thinking this is a provider issue, because I basically can not connect to the internet, but the hotmail is still working.  So my line of thinking is the phone is working cause it is obviously connecting via GPRS.

But now Im starting to think it might be the phone, because why would the provider cut me off from everything put a POP3 connection. 

Any thoughts?

I do not have access to WiFi at the moment.  I did remove my work email, I thought maybe that could be the issue cause when you set it up, they have a remote administrator to force you to use the number pin instead of the trace unlock.  So I thought maybe they did some sort of settings change.

Im about to back up my data and do a soft reset.

Yeah data connection switch is with froyo.
