One of the things that I was very curious about when it came to native Email, Contacts, & Calendar on the PlayBook is if those apps would work over Bridge. I am happy to report that all three of them are working just fine over bridge and are just marginally slower than Wi-Fi which is impressive. I am not sure how much data they are eating up on my limited data plan but I am loving it so far.
When RIM gave us a demo of PlayBook OS 2.0 I could not get a straight answer from them on if these native apps would work over bridge so you don’t need another data plan. I am so happy to report that it looks like you will not need an extra data plan or tethering plan!
Let us know what you find!
