i OS 9 is said to feature performance improvements that may help the aging device function more smoothly, and initial tests suggest that it did not significantly impact available space.Other A5-based devices will also support i OS 9 including the i Phone 4S (five major i OS versions), the i Pad Mini (four major i OS versions) and i Pod Touch 5G (four major i OS versions).The device was available initially with three storage sizes, 16, 32 and 64 GB and two varying connectivity options, Wi-Fi only or Wi-Fi and cellular.
the price of these applications is set by the developers.
Like all i OS devices, the i Pad 2 can sync music, videos, apps and photos with a Mac or PC using i Tunes, although when using i OS 5 and later, the user does not have to connect the i Pad to the computer.
Its basic design formed the core of the first i Pad mini, which had the same screen pixel count and similar features at a smaller size.
The i Pad 2 has been able to run six major versions of i OS, from 4 to 9, the only i OS device to be able to do so.
Frequency response: 20 Hz to 20,000 Hz Audio Formats: HE-AAC (V1 and V2), AAC (8 to 320 kbit/s), Protected AAC (from i Tunes Store), MP3 (8 to 320 kbit/s), MP3 VBR, Audible (formats 2, 3 & 4, AEA, AAX, and AAX ), Apple Lossless, AIFF, and WAV; support 5.1 Dolby Digital Surround pass-through Multi-touch touch screen, headset controls, proximity and ambient light sensors, three-axis gyroscope, microphone, magnetometer, accelerometer, assisted GPS cellular (3G model only), micro-SIM card tray (3G-GSM model only) The i Pad 2 is a tablet designed, developed and marketed by Apple Inc.
Compared to the first i Pad, as the second device in the i Pad line it gained a faster dual core A5 processor, a lighter build structure, and was the first i Pad to feature VGA front-facing and 720p rear-facing cameras designed for Face Time video calling.
Although it was praised for its hardware improvement, such as the new Apple A5 chip, the software restriction on the i Pad 2 and i OS in general drew criticism from various technology commentators.
A popular product, with a lower screen resolution and performance than the two Retina models that followed it but a lighter build and longer battery life, it remained in the Apple line-up as an entry-level i Pad model for three years until March 2014, latterly with a silent upgrade to a die-shrunk version of the A5 processor.
This makes the i Pad 2 the first i Pad and only i OS device to support six major versions of i OS.
