Hello. I finally pulled the trigger on buying the 650. Originally wanted to buy the 680 but couldn't pass on the cheap deal for the 650 on Cingular.com. anyway, I was wondering if you guys would recommend me getting the data plan or the Enfora Wifi sled? I'm still an undergrad and our buildings are covered with wifi. So I thought that i should go the wifi route because enventually the sled might pay off compared to the unlimited data plan through cingular. If i get the sled, will i be able to have my 650 use the wifi and not the GPRS to access the web? Any other inputs? Thanks!
