I have heard that at&t has unlimited data plan come 2011 im not sure though if germany is included with the plan. Happy New Year everyone!

You obivously have never been outside the US, neither have you heard of roaming fees. Your advice to use data on roaming can actually ruin people!
[It] is just an app to place phone calls through VoIP (internet-based telephony). It's good to make cheap phone calls, but it still requires 3G- or WiFi-connectivity to establish an internet connection, which in fact it does NOT replace.
Also AT&T data plans do NOT include data usage abroad. Actually data usage on roaming is astronomically expensive.
So artbytes is on the right track when looking for a German prepaid SIM, that she can use in her MiFi device.
Btw dg7feq is right - in Germany 3G is operated by all four operators (T-Mobile, Vodafone, O2 and eplus and all the MVNOs on these networks) exclusively at 2100MHz, so this is the only frequency band your device needs to support for 3G. Outside of 3G coverage German GSM (2G) networks use GSM at 900 and 1800 MHz, which nearly every device supports (the iPhone and the MiFi definitely do).
