Stupid GSM / ATT / Idiot fan boys.
Verizon Does Not... omg I know Shocking!!! Lock out Wifi...
if it comes with wifi it has wifi... Like Att.... omg.... they do it to,,,,
Verizon locks out the gps function to load on it's Navigator program its capitalistic.... Don't like it? flash the rom you lazy stupid chimps or better yet don't waste my time spouting off on topics you know nothing about buy an Att phone with locked GPS and find out the hard way, Verizon Wireless loads UI onto all windows mobile devices but does not lock any feature outside of GPS same as Sprint, Att omg.. really??, and Alltel

The rss feeds being prohibited is in the direct case that you run a stream or support of rss feeds. Though in theory this should never be able to reach over 5 gig of data per month Verizon feltthe need to add it to the list of things like streaming music videos or file sharing.
As for the Five gig limit and the unlimited data speal this is not uncommon on any carrier sprint or att both have data cap restrictions and use the term "unlimited use" which even that term can be debated, Most companies should nmovie away form the term unlimited and to a gig standard the problem being quick boat jumping fan boys are always fast to jump to unlimited before reading the terms and conditions and in the end Verizon losses net adds and we get a whole lot of pissed off fan boys.
Anyway I'm sure you're carriers will all be happy to see you pay 175+ to jump ship and then jump ship again to you're original carrier.
Case and point read the terms and conditions if you atr unsure of what you're signing and you have 30 days for a reason if someone tells you something and you're unsure of it rtfm
