Hacks
Sanyo 4900 > 7200 Hack
The Sanyo 4900 and 7200 use almost identical hardware, if not exactly identical on the inside. Because of this, the firmware is interchangeable. This will even enable ReadyLink on the 4900. To do this you pretty much need to be a Sprint Store technician, as most TSRs will refuse to do the firmware swap.
