700kbs is considered normal for 3g. I hope you guys arent expecting more from 4g than what will be delivered. 4g will probably max at 4-5 mbs. As far as tmobile hspa+, i suspect that once more tmobile phones are compatible, it will probably slow down substantially. Edit: If you are in an area where you know verizon has better 3g, you may consider updating your prl to one that is modified for verizons towers. Instructions can be had under android development in the xda evo forums.
