MSN Wireless has not raised its rates for Internet Services.
However for Wireless, yes it has raised rates with its 1st notice to users in March 2012, with its 2nd notice with a courtesy phone call in April, May, June 2012, and 3rd notice via SMS on July 1st, which is 30 days, and on August 1st the company increased its Wireless phone plans rates.
It was the first time since November 2005. In addition, the rates are still relatively lower than other companies.
The Internet provided is through all major carriers including Cable and Fibre/DSL, including bandwidth provided by Peer1.
Hope this information helps.
