My wife uses a 3gs, still on 4.0 firmware. This week she received a message from our provider, Softbank Japan, saying that due to some changes at their end which will happen in October, she may get some issues using the phone unless she upgrades to at least 4.2.
Now I don't want to upgrade as she will be due for a replacement soon, iPhone 5 or whatever, my plan is to jailbreak, unlock and sell it...
Anyone had a similar experience with other providers?

Don't do it. Sounds like smoke-and-mirrors

Check it with TinyUmbrella to see if u can go to 4.3.3 as it is jailbreakable/unlockable if u preserve the baseband
If u don't know how to do this please ask it's also on YouTube just search for "iPhone check firmware TinyUmbrella"

IF (and that's a BIG IF) it's true ... upgrade when it's really needed or sell it and buy a new one

Same here, ps before you go about updating it I STRONY SUGGEST you ask for our help that way you don't accidentally screwup the baseband and possibly brick it from ever being unlockable or even jailbreakable
