I'm using the 1115, it's not the latest, but apparently it has the most since it has extra agreements for corporate accounts only. It's only noticeable if you're actually roaming outside of your home area anyway.
Did you notice any differences? I'm still confused as to what these do exactly. I saw your post on XDA about PRLs basically not changing signal strength and mainly are just for packet routing...
The area I'm in has a lot of virgin users and I think the servers are very congested (I'll get 1mbps+ speed tests at 2am with an average of 150-250ms ping, but then my speeds drop to below dialup during peak usage with 1000+ms pings!). I'm mostly just trying to get my ping down/stable so grooveip is usable on 3g. Will updating my PRL help with this at all?
After more research, here's what the PRL does:
Understand how the Preferred Roaming List is used
VM's 3G is very flaky for me as well, and Groove IP over 3G not reliable (it works fine over wifi though). Hopefully their throttling should relieve some congestion from the heavy data users. Or request Google Voice to start using a more efficient codec (the current one and only takesa bout 64 kbps), and Groove IP has no choice but to use that.
Did this today...what prl did you end up using? Notice any differences? I used this one - xda-developers - View Single Post - [HOWTO] Change PRL on Virgin Mobile LG Optimus V (5/06/2011) but I'm not sure if it's the newest one?
