Evidence has emerged of the latest firmware upgrade for Apple's all-conquering phone, prompting speculation that a new model may be in the works.
MacRumors has found reference to iPhone 2.1, a major advance over the current 1.2 edition. Apple often uses these leaps in number to distinguish between new models, as happened with the change from iPod Touch 1.0 to iPod Touch 2.0 last year.
So what might we expect? There's no concrete evidence just yet, but the hot money's on more storage, a better camera, a screen to rival that of the HTC Touch HD and maybe even that much sought after copy and paste function. Watch this space.
