PreCentral reported that there are some issues with GPS on the Palm Pre Plus.

The thing about putting a phone on a new carrier - even if the hardware is virtually identical - is that there are always a handful of bugs that pop up. We have two from our forums that are looking something like confirmed. They aren't critical, deal-breaking bugs, but they are a hassle.

First up, long-time member dutchtrumpet points us to this thread about Verizon MMS and the gist is this: when WiFi is on, MMS messages aren't able to be sent. It looks as though the issue is that MMS message need to go through Verizon's EVDO network, but the Pre Plus is attempting to send them over WiFi.

This isn't an issue for Sprint users thus far. The good news is that there is an easy workaround: just turn off WiFi before you attempt to send an MMS message.
