Hmm, this dataplan stuff is really strange here in Germany, esp at TMO:

If you want to combine voice and data option for one sim card you have 3G limits of 300MB per month and connection drops to 64kbit if you reach that limit.
So, if you want to listen internet radio 64kbit is not enough and 300MB volume is nothing, if I check my imap account regularly 300MB is also nothing. And *I think* if you use the big 3G dataplan option (5 GB/month) you can not combine this with a multisim option, for what reasons ever.
So far I will use my current +200kbit/unlimited EDGE data plan + openvpn proxy to break the internet port limits and check if the data Day-Flat is an option. 200kbit is fine for internet radio.

Looking at 1&1 you can get Vodaphone-net + 3G 1GB/month reduced to EDGE(!) as part of their all-in-one offer

But Vodaphone has no good multisim option - if you want/need one.

But look at the small numbers!! If you use the Smatphone as modem you will be a poor person in a short time :-)

When using the N900 can I change easily between EDGE and UMTS if I have two APNs?
