As an update to the power management problems I first posted about - I flashed to MR5, stock Sprint, and two of Juicy's recent ROMS. Problem did not appear in any ROM except MR6. To refresh memories, the spin on this I had was when I cradle my phone in my vehicle I set power management to NOT dim or turn off the phone.
A different, unrelated issue I had was the touchscreen was useless in landscape mode (hardware issue - affected ALL ROMS tested). For that, I had the phone replaced at the local Sprint store after flashing back to stock + relocking of course. New phone in hand, I tested power management to make sure it worked like it was supposed to. It did. Got home, immediately unlocked it and gave MR6 a reflash. Worked like a champ with iGuidance again and I have left it alone since...
Well, almost.
I reinstalled TrackMe and once again my trusty Touch Pro was doing double duty as my kayak's little black box. Here's the paddling path my phone's GPS recorded during my playtime in Boston harbor among the Tall Ships :
Hah. And you guys just thought it's a phone/AV player & recorder/gametoy/email/chat/webbrowser/alarmclock/flashlight/addressbook/stock ticker/wifi router/calculator/hand warmer.
Appreciate the hard work Mike! It isn't easy keeping all of us in love with our Hermans.
