First my questions: If I wanted to shelve my Thunderbolt until Verizon finishes an OS update, and ESN swap another (3G CDMA) device in place... 1) how would I swap back to an LTE device (My Thunderbolt) 2) would I lose my "unlimited" LTE data plan, and end up with a capped plan? 3) can the swap be done via the website? (it looks like I can swap to a CDMA device on the site, but not sure about swaping back to an LTE device) 4) should I expect any difference in billing\contract terms\bla bla. New to Verizon, not sure what crap they'll pull for something so simple. Why: - you can stop reading here if you just want to answer the above I've had two Thunderbolts since launch, both with issues. When LTE works, it works amazingly well (36MBs down\16MBs up in my appt in San Francisco (Market & 14th St). Generally calls work fine here at home. BUT Data, GPS are highly unreliable. I use google voice for SMS, so it really bugs me when I pull the device out of my pocket to find out, I've not had data service for hours. Problems: Data The major issue I have is, I loose ALL data service very frequently. Here is a perfect example of the problem, go into subway, loose all service (ok) come up to ground level, get 4 bars of service, but no data. Should have LTE. Fire up browser, magically I have 3G, then LTE sometimes - sometimes I need to reboot before I get anything at all. Voice\Audio I've had a few dropped calls in areas that I wouldn't expect them, which I feel is kinda nit-picking but with full reception at off peak hours, while not moving? Come on. I use less than 250 min a month, so for this to happen... seems more than a fluke, but whatever. Generally, coverage has been less than I expected. I see others talking on their VZW devices in areas where I have no service. Coverage is no better than my work phone on AT&T (and I'm in San Francisco, where ATT is pretty poor) Tethering - if I have anything less than 3-4 bars, tethering kicks on\off, on\off, on\off, and then I get annoyed and give up. The device continues to act funky- have to reboot. Annoyed. If I have full service (4 bars) Tethering works amazingly well. Tried tethering in a 3G only area, and had the same issues. Doesn't seem specific to LTE. Tried with CDMA Only turned on - same problems. GPS Sometimes works great, other times can't get a fix. Annoyed. While using Navigation with Google Maps I can't get screen to STAY off. I could on my Nexus One. On TB I start navigation, hit power button and the screen briefly goes black, then comes right back on. This of course leeds to a dead battery in really short order. Why? What I've done so far: Wiped the phone (many times) Changed eHPRD (now instead of 1x I have 3G occasionally, but more often no data at all.) Changed Preferred Network Type to CDMA Auto PRL, still have same no data issues though. Data roaming is enabled, as is mobile network. Tried PRL updates (ineffective I believe with this type of device) Reset GPS Cache with GPS Status App (useless - did NOTHING) Replaced the device (same issues) No weird apps installed, not very many apps at all (save for the crapware) Opened trouble ticket with VZW, waiting on response (very nice phone support, but we'll see the result. Have NOT rooted\installed the unofficial update circulating around. I'm a purist. It needs to just work with stock, carrier tested & approved software, without me waiting endlessly for them to release a patch. Have had issues in the following cities: San Francisco, Phoenix, Chicago Metro, DC, San Diego, San Luis Obispo, LA, San Jose. Worked fine (3G worked well in Honolulu, issues with GPS though- Doubt they have LTE coverage yet). Device Specs: Android version: 2.2.1 Baseband version: 1.16.00.0223r Software number: 1.12.605.6 PRL version: 15011 Summary When it works, it works really well, mostly at home where I don't care about data service. When traveling, I can't count on it, and that really frustrates me. I would rather have a reliable, slow device than this, hence the questions. Thanks for listening to my whines, sorry for the length.
