huawei e220
 

Had this a few weeks and have to say its a Great bit of kit. :D

Works on windows and osx (drivers for windows are actually on the device itself)

Currently In an area that according to t-mobiles website has variable coverage where if i Look at the map there's a black spot which happens to be just about where i am :rolleyes: signal on most of the networks here is variable at best, infact when I manually scanned orange was the only one where i could even see a 3g signal

It did take some positioning to get it to stay connected (i found a spot where it seems to work well)

but credit to this little device 0 bars of signal and yet its managed to maintain a Stable GPRS connection for nearly an hour now :D

For GPRS speeds arent bad either constantly hitting about 50kps which although slow is at least allowing me to talk on MSN and surf. and its marginally faster than my 56kps modem usally connects at ;)
