I realize this thread is a little old, but there isn't much activity in this sub-forum...
That said, I would suggest checking out the newest releases of GummyJar Nexus! I have been using GummyNex very consistently since 0.9.x and I have never had any serious problems/bugs!
The most current stable release is 1.2.5 and it includes imoseyen's newest LeanKernel 3.8.0 which has all kinds of wizardry in it and really strengthens the ROM itself!
I find the best combination for me to be:
GummyJar Nexus 1.2.5 ROM + Included LeanKernel
- ROM Toolkit PRO
- Titanium Backup PRO
- APEX Launcher PRO
(the free versions of ROM Toolkit and APEX are included with GummyNex, but I like the Pro versions better; plus, I like to support devs when they make such amazing apps!)
I have experienced significant signal improvements ranging from as little as 10% (in already super-strong areas) to as much as 500% (such as near my house), based on an average of 5x download/upload SpeedTest.net results. I haven't had my phone force-reboot in at least a month and a half (knock on wood), haven't dropped a single call, and maxed out my download speed at 39.5Mbps and upload at 19.8Mbps!!
The only problem I have is that my Browser force closes VERY often... :/ I don't know what the deal is, but if I have more than a couple tabs open, and open one in the background, it will freeze and give me the "wait or close" option box. Weird thing is, it doesn't happen all the time - in fact, I can go two weeks with it happening maybe 1-2x total despite constantly having 5-15 tabs open at once, and then suddenly it will happen for a week force-closing 5-15x/day ??? Very frustrating! I don't think it's the ROM's fault, though.
