Hi all,
I've read through the plethora of iPhone threads here (very helpful, thanks) but still have a few questions. Hoping that a thread like this might help members in the future too.
Basically, I'm heading to Canada/US next week, and if the exchange rate stays good (fingers cross yesterday's events don't have an immediate impact), I'm thinking of picking up an iPhone. TBH I still don't know if it's the phone for me, but I figure if I don't like it, I can sell it here and hopefully not lose out too much.
I do have a few burning questions though, which I'd appreciate if one of our resident gurus could answer.
Firmware
I understand v1.1.2 has yet to be cracked. So I need to buy a v1.1.1 (or earlier) model - which is a week 44 or earlier model, identifiable by the s/n. So as long as I buy a week 44 or earlier, I'm OK? Then, using guides like
this one, I can upgrade to 1.1.2?
Voicemail
I understand visual voicemail won't work, but there's nothing stopping me from calling 121 (Vodafone voicemail) and retrieving my messages as I currently do, right?
Bluetooth
Everyone says it sucks. Why? Range? Features?
Basically, I'll want to transfer files (and sync) from Mac->iPhone via Bluetooth, and I'll also need to use it with my SonyEricsson Bluetooth carkit. Any problems there?
Unlocking
I've read far too much about too many different methods.

IPSF ($$$), Jailbreakme, AnySIM...it's all very confusing. Which of these is considered the "best" method? I'm not averse to a bit of software hacking, provided I'm given a good, step-by-step guide...but hardware hacking is something I'm not keen on.
Data
Is it possible to entirely disable all GPRS data through the phone? This isn't a huge deal, as with my Vodafone cap ($79 Supercap, pre-paid) I get about 1mb per month before it blocks all data...but still, I'd like to be the one who decides when to use that data.
Number format
Not a big deal, but do I need to use a specific unlocking method (or other hack?) to make it display Aussie number formats (ie: 04xx xxx xxx)?
Ringtones
Once unlocked, I can use any Mp3 or AAC as a ringtone, right?
Tough?
How tough is the iPhone? I like to keep my phones in either my suit jacket top pocket, or pants pocket (ie: jeans or trousers). Do they have problems with easily-crackable screens, like the first Nanos?
Software
Now that Apple have opened the iPhone up to 3rd party apps, I assume that aspect no longer needs to be hacked?
Calendar
Assuming I can add calendar events and reminders directly on the phone? (This is something I do all the time with my current SE K750i).
Thanks all. As I said - I've read a fair bit, but much of it has left me very confused. Appreciate any help.
Cheers,
- Febs.
