Today, Apple finally pushed the new and highly anticipated iPhone 3G to customers worldwide. For owners of iPod Touch and iPhone devices, today is the day you can download the 2.0 version of the firmware. For iPhone users, the upgrade is free but for iPod Touch the download is priced at £5.99.

Apple are required, due to their accounting procedures, to charge for updates to the iPod Touch as the revenue from its sale is recorded in the accounts all at once where as Apple accounted for the revenue from the sale of an iPhone over an extended time.

Now that Apple are moving to a subsidized model without a recurring revenue stream, will we have to pay for any future upgrades? Will Apple account for the iPhone 3G like the Apple TV and be able to offer free software upgrades in the future or will iPhone Firmware 3.0 cost us all (excluding ‘iPhone Original’ owners) a few pounds?

I’ll update you as soon as I find out…
