Over the years I cannot count how many times I have had to explain the convoluted ways that a BlackBerry can use to connect to the internet. Everything from WAP to WAP2 to TCP/IP to BIS to BES to Wi-Fi are just not that simple to describe. Every new BlackBerry developer needs to understand this so their applications can make a reliable connection to the internet. Sadly RIM has yet to provide a comprehensive guide to those not in the BlackBerry Alliance.
From now on I have a solution. Peter Strange has posted a brilliant thread on the official BlackBerry support forums detailing how BlackBerrys connect to the internet and all the issues a developer must deal with. Its a great starting point an may solve most of your questions.
Check out his thread at this link and let me know if you found any other good development resources!

I’m an iPhone user for almost 2 years now. Everyone around me in the office are starting to use BB. Not sure when I can hang on to iPhone
