Other than the cost, there's really no reason to continue to use an i Phone 4 at this point. That gives you the best of both worlds: you'll get a fresh, fast new phone with all the latest hardware features and the latest version of the i OS.
I'd much rather pay for those new things than have a poor experience on an old phone.
Apple's penchant for cropping text labels remains frustrating, though, and is increasingly common throughout the OS.
If you updated your i Phone 3GS to 5.1.1 and it was previously unlocked with the 6.15.00 baseband, you probably noticed that it wont pick up signal anymore and it just says “searching…” and eventually “No Service” even if there is no sim card in the i Phone itself.
However, the older the kit, the less of i OS 6 you actually get.
Our test kit is an i Phone 4, an i Phone 4S, an i Pod touch (fourth-generation), an i Phone 5, an i Pad 2, and a new i Pad (courtesy of Vodafone).There are more new features than you'd think, even when you don't get all the new features.A common criticism of i OS is that Apple never radically updates it.This is more visually appealing but muddies the water when it comes to alerts that were once made in part through a change in colour of said status bar.Better amendments are the new audio controls on the Lock screen and Spotlight search results now displaying the name of an app's containing folder.Apple's You Tube app has gone (Google has since released its own on to the App Store) and Maps now runs with Apple power rather than Google juice.Elsewhere, the OS is more social (Facebook now joining Twitter in being baked in), Siri's been improved, and countless tweaks (some fairly major from a usability standpoint) are in evidence in the likes of Mail, Safari, Phone and the i OS stores.Oh, and Apple finally added a clock app to the i Pad, which resulted in a legal spat with the Swiss railway network service.It seems not only Samsung is in the photocopying business.i OS 6 ditches support entirely for the original i Pad, but is nonetheless compatible with a surprisingly wide range of devices; i Phones back to the 3GS are supported, as are both the fourth- and fifth-generation i Pod touch.The latest models, the i Phone 8 and i Phone X, have a lot of great features.If you're looking to spend less money, the i Phone 7 (read review) is still available for lower prices.Several people have been reporting Wi-Fi problems after updating to i OS 6 on both i Pads and i Phones.The connection might work sometimes, but it usually cuts out or takes forever to connect to anything, only to time out shortly after.I always recommend buying the newest and best phone you can afford since it will last the longest.
