Blackberry connections

Do not understand why BB makes a Http connection so complex, but still need to face it.

If you were trying these methods, then the preferred order, based on various posts on this forum, seems to be:
1) BIS-B
2) WAP 2
3) Direct TCP
4) WAP 1

This is the best post talking about this topic
