I've just fixed a nasty bug in the text that made a lot of text undisplayed in the “GPRS behind the curtains” section. Sorry for not spotting it earlier.
BTW, the article gives an excellent overview of setting up GPRS connections and, in addition to this, discusses the following apps:
FSC E2c Pro 3.0
pocket PhoneTools 4.1
DialupMaster 1.7-d23 (excellent scripting capabilities!)
Mobile2Wear network manager 1.0 (I've found this very buggy, avoid it!!)
Sorry for not including it in here - I'm tired of maintaining the same article in 6-7 different forums at the same time.
