Apple iPhone 4

At the heart of the device lies Apple's A4 chipset (45 nm) with a single-core 1.0 GHz Cortex-A8 CPU and a PowerVR SGX535 GPU, providing enough power to perform everyday tasks. This model comes with 512 MB of RAM and has various internal storage options of 8/16/32 GB but lacks the capacity for memory card expansion.

The iPhone 4 showcases a 3.5-inch LED-backlit IPS LCD capacitive touchscreen with 640 x 960 resolution, delivering an impressive 330 PPI density for sharp and clear visuals. The screen features Corning Gorilla Glass and an oleophobic coating for durability and smudge resistance. It also features sensors like an accelerometer, gyro, proximity, and compass for a variety of functions.

Photography on the iPhone 4 is facilitated by its 5 MP, f/2.8 rear camera with autofocus and LED flash that is capable of capturing 720p@30fps videos. The device also has a VGA front camera designed for videocalling over Wi-Fi only. Both cameras perform adequately for casual photography and video calls.

For long-lasting performance, the phone is equipped with a 1420 mAh non-removable Li-Po battery. Battery life is rated at up to 300 hours of standby and up to 14 hours of talk time on 2G, or up to 7 hours on 3G networks. It also provides up to 40 hours of music play. The iPhone 4 uses a Micro-SIM card.

Connectivity options are comprehensive with Bluetooth 2.1 (A2DP), Wi-Fi 802.11 b/g/n with hotspot capability, a USB 2.0 port for data transfer and charging, and GPS with A-GPS. It doesn't have NFC capabilities. Sound quality is enhanced with active noise cancellation using a dedicated mic, and the device retains the classic 3.5mm headphone jack.

Convenience features such as an oleophobic coating and scratch-resistant glass back panel speak to the device's durability. The iPhone 4 originally shipped with iOS 4 but can be upgraded to iOS 7.1.2, offering a range of updated functionalities over its initial release. This device maintains a respectable SAR (Specific Absorption Rate) of 1.17 W/kg (head) and 1.11 W/kg (body), with slightly lower values for the European market.

With its price at 200 EUR, the iPhone 4 remains a timeless piece of technology that caters to users who appreciate the vintage Apple design and reliable performance.
