O2 are doing a deal where it's 21.50 a month for 100 mins 500 txt and 500mb internet on a 24 month contract with a free IPhone 3GS 8GB Version.

Just wondering if this is a good deal?

How long warranty does the IPhone 3GS come with?

Thanks

Will come with the standard apple one year warranty. However be warned that apple pretty much dropped support for the iPhone 3G when the iPhone 4 was released. It's highly likely apple will drop support for the 3GS when the 5 is launched next month or more likely in september depending which rumoured release dates you believe. Whilst the phone may still work (though the 3G struggled with iOS 4.0 as the 3GS will likely do with iOS 5) it is possible some apps will not be supported on older hardware or older versions of iOS

Yeah, I wouldn't get it personally - it will be 2 generations old within the next few months.

When Apple drops support for the 3GS in the next few months the best thing to do will be to Jailbreak it. This will give you more updates and greater functionality then the restricted firmware Apple inflict on their users.

That's a nice theory, but based on the fact that new OS versions tend to introduce new features which older hardware has trouble running, you'd still be stuck with old tech. It's like a Windows PC, yes you might be able to get Windows 7 to run on a 5 year old laptop, but unless it's very high spec, it probably won't be a great experience.

Based on the restricted update to iOS 4 that Apple released for the iPhone 3G because the hardware wasn't quick enough to run the full iOS 4 update, I'd say Apple aren't doing this to be difficult or to force upgrades, they're doing it in such as way as to keep the user-experience as good as it can be for that particular model.

Thats true. An OS will always become more bloated.

The original iPhone 412 MHz ARM 11 with 128MB RAM
The 3G had 412 MHz ARM 11 with 128MB RAM
The 3GS runs a 600 MHz ARM Cortex A8 with 256MB RAM
The iPhone 4 has a 1 GHz ARM Cortex A8 with 512MB RAM

Given the trend is towards 1.2GHz dual core CPU's this year it will make the old iPhones look an embarrassment. Something you would rather keep hidden in your pocket rather than flashing it in front of people to try and make everyone think your cool.
