Third Party apps changing GPRS to gprs

Can someone tell me why my network status will change from GPRS to gprs every time I use a third Party app trying to access/use network(e.g Opera,nrange GPS,iBrowser) which is causing BlackBerry services to stop working unless I do a Battery pull.How can I solve this Problem?or did RIM include this in OS 4.5 because I never Had this issue with OS 4.2?

The same thing happens to me, but seems I found the solution. As long as it finds TCP with Access Point Name, it will use it. So just wipe off everything in the TCP and save, it leaves the TCP and use service book
