3 Mobile Broadband UK / Treo 600

Posted by SpooForBrains
3 have just opened up their mobile broadband to us plebs (pay as you talk). Up until now I have been using my Treo 600 with O2 pay and go which allows me to do pretty much nothing and charges me for the privilege ...

So, does anyone know whether I'd be able to buy just a pay and go SIM from 3, put it in my Treo 600 and take advantage of the mobile broadband (obviously not at 3G speeds)? If so, what can I expect? Do they cripple their mobile broadband service and if so, how?

Thanks!
