+1 wifi router. i use wifi router also and get pretty decent speeds. Great app and i have internet on the go even in ****holes like mcdonalds who try to charge you for wifi.
The problem with WMWifiRouter is the battery goes bye bye real fast.
As I noted, you will probably have to plug your phone in to your computer to charge it. But, you won't have to go through all the configuration rigamarole.
