Guys this may be a stupid newbie question but...

I bought IM+ yesterday and have it all setup perfect.

Only problem is as soon as the treo650 screen goes off it disconnects..

Ive checked the power settings and I have power set to 3 mins..

Im not sure if its an IM+ issue or in fact I havent setup the power options on the treo to stay connected to GPRS ???

What am i doing wrong
