Hello all,
I'm posting here in hopes that someone could help shed some light on the matter before I give up and send my phone in for repair, provided it will be repaired/replaced given how random this issue is.
I've had an iPhone 4 since November 2010, a GSM unit as I'm in Europe. Jailbroke it on a dull day just to see if I'd have any use for that, restored it to stock firmware (using the backup I had created before applying the jb) about 24 hours later. No trace of jb on it at all nowadays, basically. The phone and the system are as vanilla as they can be. The only customization, so to speak, is the provisioning profiles in my name as I'm an iOS developer.
Ever since March, the phone will sometimes randomly reboot. There is no pattern whatsoever: I may be fiddling with it, I may be keeping it in my pocket, it may be charging, it may be placidly sitting on a table undisturbed. Out of the blue, the Apple logo will show up and the thing will reboot, and won't ask for the PIN either. I hadn't thought much of it as it was very rare, but lately it's become more apparent and I decided to look for some logs.
To my horror, I found that ~/Library/Logs/CrashReporter/MobileDevice/Jolliphone/Panics on my Mac was way overpopulated. The weirdest thing is that all the logs look virtually the same, although they all end abruptly in different points (which suggests that they were so brutal that there was no "time" to write the whole thing down.)
Here is an example:
They are all like that. The only thing that's different is the OS system, which ranges from 4.3 to 4.3.3, and the location that generated the panic:
…and so on. The caller is always 0x8007f3e5, and the buffer location is always in 0x0d6…–0x0d7… range. This is what leads me to think that it may be some memory problem.
As I said there is absolutely no pattern in this. Sometimes it will stay a month without panicking – after a few panics on April 1st, it happened again on May 2nd – yet in other occasions it will panic 4 times within 8 minutes as it happened yesterday morning.
Lately it's been happening more often when I charge it using the wall adapter, but then again it's fairly inconsistent: I have kept it connected since last evening on purpose, and it hasn't panicked once.
I have tried restoring it as a new phone, just to make sure that it wasn't a software problem, and the very same thing happened as soon as I connected to my father's iPad 2 adapter.
If you have read so far, I want to thank you very much for your patience. I'll get to the point: what should I do?
I spent 35 minutes on the phone with AppleCare this morning and was about to give the green light to have it picked up, but the woman told me that I couldn't provide the logs to tech support, and that they'd run some tests on their own and, if they could reproduce the problem, I would get a refurbished phone in place of this one, otherwise they'd send the same unit back. Considering that it's impossible to reproduce it on purpose, I'm afraid that I will just end up being phoneless for two weeks (with the added issue of finding a way to stick this micro-sim into a phone that takes regular-sized sims), and ultimately be sent back the faulty phone.
I told the woman I'd consider going to the Apple Store in Rome, so I could at least speak with a human person and expose the problem in more detail. I do have a repair ID and apparently I can just book a slot at the genius bar and have them access the repair ID data.
The problem is that I live 200 km from Rome, and it would take the better part of a day and it would be more money spent on this issue to get there and back. And I wouldn't even be certain that they'd replace it: even if they agree to replace it, what if they're out of stock on 32 GB units, for instance?
So here is the dilemma: I have a phone that feels very unstable given the 18 (eighteen) panics I've had in the last three days, and I'm facing either wasting time and money to go to an Apple Store, or being without the phone for the better part of two weeks, again without any certainty.
Going to my carrier (Vodafone) is pointless: they referred me to Apple; at most they will ship it for me, but at that point I'd rather do it myself.
As for the local Apple Premium Reseller, they are an authorized support center for Macs, but they don't offer any support for iPhones at all.
What would you do?
Thanks.
