I have given in trying to configure my i-mate SP3 manually to access the internet using Dialog GSM. I have followed the instuctions on their web site for GPRS, contacted an on-line support person and I am still unconnected. The phone part works fine. Just no internet access. The on-line support person was very helpful though and suggested I take the phone into a Dialog GSM support center and they'd configure it for me there. So either a job for my wife Helen tomorrow or for me on Saturday.
The on-line support was pretty good once I got it to work. It basically gives you an on screen web chat window a bit like a very basic MSN Messenger. The first time it just timed out. The second time a browser window showing Dialog GSM's home page on came up and covered up the chat window so by the time I noticed the chat window the support person had signed off. The third time though I was ready, immediately closed the irritating popup window and managed to get a few things to try from the support chap at the other end.
I shall post an update at the weekend with full instructions on how to get connected, assuming I am :)
Update, as promised, I now have my i-mate SP3 connected to the internet through Dialog GMS's network in Sri Lanka
