Bidding AT&T Adieu: Hackers Release iPhone 4 Unlock

By Nick Mokey August 4, 2010

Have a jail broken phone? Make sure to check out our picks for the best jailbreak apps and games.

Just days after opening the iPhone to non-Apple software with the simplest jailbreak procedure yet, hackers have further liberated Apple’s iPhone 4 with a carrier unlock, which frees owners from AT&T by allowing them to use their iPhones on any GSM network.

After jailbreaking an iPhone 4 with the simple, Web-based unlock released earlier this week, owners can download an updated version of ultrasn0w that now works on the iPhone 4, iPhone 3G and iPhone 3GS. It’s available for free today through Cydia, an app which acts as a distributor of software (similar to Apple’s own App Store) on jailbroken devices.

As with previous iPhones, a jailbroken and unlocked iPhone 4 will be able to make voice calls and access the EDGE data network on T-Mobile, but does not support the frequencies required for 3G speeds. (AT&T uses 1900MHz for 3G, while T-Mobile uses 1700MHz and 2100MHz, frequencies the iPhone 4 does not support.)

Another report suggests the iPhone 15 Pro will be pricier

Apple is expected to manufacture a slightly smaller number of iPhone 15 handsets compared to the iPhone 14 last year, but the company is eyeing an increase in revenue when the device launches in the fall.

How? Because it’s considering increasing the cost of the iPhone 15 Pro models.

I lost my iPhone on a dream vacation — and it wasn’t a nightmare

Photo of Spain.

Our trip to Spain and Morocco, which my wife, Julie, had meticulously planned for 15 months, started off rather inauspiciously on June 25. After arriving in Chicago from Portland, Oregon, we learned that our connecting flight to Newark, New Jersey, had been canceled due to weather concerns. As we waited in line for two-and-a-half hours to talk to a United Airlines agent, we were told via text by a customer service rep that we might be stuck in the Windy City for two days.

A 30-year Spanish teacher, Julie was on the verge of fulfilling a lifelong dream of visiting Spain. Now, several activities were in danger of being erased from her bucket list as her worst fears about the trip were being realized. When we finally made it to the service desk, our hope was all but snuffed out. We explained the situation to the agent, who spent several minutes looking at his computer wordlessly. He eventually looked up and said: "I can you get out on a flight tonight."

How to fast charge your iPhone

iPhone 12 Mini with charger

While they may not be some of the longest-lasting smartphones on the market, modern iPhones boast more than respectable battery life that should be able to get you through an entire day's use without breaking too much of a sweat. Of course, that assumes a lot of things — including a battery that's still relatively new and in good health, plus a usage pattern that doesn't include all-day streaming or gaming.

If you fall into either (or both) of these categories, then overnight charging isn't going to cut it, and you'll want to get your battery topped up again as quickly as you can so you can get back on the road. Thankfully, every iPhone released in the past six years supports much faster charging, but the downside is that with very few exceptions, Apple has never supplied you with the right adapter to get the best possible charging speeds from your iPhone.
