I have read up on these things I have had a jailbroken Ipod for ages now. I just wanted the themes. I do read but sometimes google doesnt always have the answers. If I have to go without a phone thats fine I was just asking as this is the first time I jailbroke my Iphone. I have only done the jailbreaks with my ipods. I do not believe I made any mistakes I just purchased the phone like a week ago. So w/e firmeware or BB was on it was out of my control if thats what you are talking about. I just read about the jailbreak yesterday and decided to do it last night. I do not DL anything unless I read about it first which is what I did on my ipods. Or I come on here and ask questions or look for similiar questions. So I am not being stupid and mess up my phone cos i would die without it.
Your answers were on the first page of threads in this forum, so forgive me if I doubt that you checked things out before taking action.
And you've had both a brand new never updated 3GS
and an iPhone 4 for a week? That's basically what you've written, though I'm guessing the 3GS either came from someone else who updated it or you indeed have had it and did upgrade it at some point. But going by what you said, if these phones were both new and you were counting on unlocking at least one of them, then yes, you did make a mistake by not making sure at least one would be unlockable before you bought them. There are plenty of secondhand 3GS models on the market with the correct baseband for an unlock.
Making mistakes is how smart people learn. They're nothing to get defensive over and not necessarily a mark of stupidity--if you're willing to learn from them.
End of lecture. Now for something that might be helpful.
BiteSMS offers international texting via an internal "credits" system. You can use it for regular carrier texting as well, but the credits may be an option for you overseas even if your phone is not unlocked. You'll need to see if they use data and how much, because I haven't researched it that deeply. But perhaps if no unlock comes through before you leave, you can purchase AT&T's smallest international data roaming plan along with some Bite credits and just be very careful about watching your consumption. We used the AT&T $20/20 MB plan this last year in Europe (without Bite) and didn't come home to an overly outrageous bill. We did make sure to turn cellular data off unless we absolutely needed it.
If you think you'll need to do this, contact AT&T well ahead of time to figure out exactly how they'll bill you, as they prorate these things around your billing cycle dates. You want to be sure you don't go over during the prorated days, this was one thing I didn't do, and it did cost me an extra bit of cash when I went over--I was still under the 20 MB overall, but I didn't realize the first few days of my trip were prorated until the cycle date change, so I went over for those days.
The latest version of Bite should be available through Cydia later today, and their website should contain all you need to determine if it will be helpful in your case. I do highly recommend it though even if it won't work for your trip, it's an awesome program for people who do a lot of texting as it's packed with features you don't get with the stock Messages app. There's a free trial, and you have the choice at the end of either continuing free, with ads, or paying for the app with no ads. Best money I've spent post-jailbreak on an app, and I use it all the time with my regular messaging plan.
Good luck, and hope you have a terrific trip!
