Which xda to get?

[st3836]

I have a requirement for a PDA which is connected to the internet and can connect to our business server.
I think that the XDA is the right one but want your opinions based on the following:

We will be using about 30mb of data each month, which network is cheapest for this and also voice calls?
Any ideas?

If you are in the UK I suggest that you speak with O2 Business Sales as they have done some good deals on handset price if you have high data usage.

I do not have any specific figures but it should be worth talking to them.

In the US, (a) you can't get the XDA II from a Carrier so I guess around here we'd recommend the XDA, and (b) T-Mobile will give you unlimited GPRS for $20 when you have a voice plan, $29 without. The $29 plan includes voice, but it's pay-as-you-go with no package minutes.
