Hi,
I have had my 6210 for a few months now and I find it a truely excellent product and cannot recommend it highly enough. I use it to get e-mail from my 6210 as well as browsing the web. I also have the WAP on my Psion as well as on the phone which makes 'WAPping' easier. The functional design and the features are better than on the 7110.
As for the high speed data link I think I do not have it enabled. I beleive you can only get it in the UK on the Orange network and it costs an extra £5 per month.
If you want any more info just contact me
