Wireless plans

Any recommendations for wireless plans? The Drupalcon site recommends t-mobile, but I found them to be crap when I was at BADcamp. (Usually only 2G speeds.)

I'm using an iphone 5.

If you are Fido customer from Ontario you get $7.99/50MB for 24hr. If you exceed 50MB you get charged additional 7.99 until the 24 hr expires.
Once 24hr period expire you can start a new one under the same conditions.
