No sure this will work as it just come across my mind. I went into setting>wireless..>APN, then create an empty apn acc, then i just checked it. As before this, we usually checked on Maxis (so tt we hv net access). By create an empty acc (ie no pw, no server to connect to) tt shd guaranty no hiding or quiet backgrd gprs transmission. I know there is app tt can switch off th Apn, but i tot this might work. When wanna use gprs, just go & flagged back to Maxis Apn. What u guys think of this method?
