How is page plus on iPhone 4?

I Want to get page plus for my Verizon iPhone 4 and I'm wondering how are the internet speeds in San Francisco California? & does iMessage work?

You can learn more about PagePlus Cellular from their website: Prepaid Cell Phone Cards | Prepaid National Cell Phones

PagePlus uses the same exact towers as Verizon Wireless so the nationwide coverage is almost the same. In fact you can use Verizon phones without flashing the phones in most cases! The App Store, email, and web should all work over Wi-Fi but to get the phone to work on a 3g connection might entail messing with the configuration and settings of the phone.

Because PagePlus Cellular is piggy-backing off Verizon's towers, I think Verizon has some control over what phones will be allowed on the PagePlus service. I read that Blackberry phones are not supported on PagePlus Cellular. But I've also read of Palm and Droid phones on the service!

That's the reason for this post. I just wanna know if Verizon's iPhone4 works on PagePlus Cellular:-)
Let me know!
