Touch Pro 2 (Sprint) wont switch back to EV sometimes

[mjh8812]

ok so has anyone noticed running the stock sprint radio on the touch pro 2 that for instance if a data transfer is taking place, for example im using slacker radio..and i get a text message and it switches back to 1x..it sometimes does not switch back to 3g unless the connection stops transferring for a few seconds...if its a steady stream of data it will stay on 1x it seems like forever..is there a fix?
