4G vs. 3G vs. WiFi Throughput For Samsung's Epic 4G

Some of the most popular Android smartphones currently available are members of Samsung's Galaxy S line. Powered by Samsung's own 1GHz ARM Cortex A8-based Hummingbird processor with a four-inch Super-AMOLED capacitive touchscreen, it's no wonder Samsung has sold over 5 million Galaxy S phones. The Epic 4G variant of this phone, available through Sprint, is also one of the scant few 4G capable devices on the market currently. Sprint's 4G network utilizes WiMAX mobile broadband, with a theoretical maximum throughput of 40Mbps. Sprint claims that the average download speed on its 4G network is between 3 to 6Mbps, with peak download speeds above 10Mbps. The performance figures seen here actually show solid throughput for the Epic, besting competitive 3G devices and even versus some with a Wi-Fi connection. 4G WiMAX service is still rather limited geographically, but hopefully devices like these will help to kick the roll-out into gear a bit.

Can Apps Really Damage a Cellular Network?

"In FCC filings earlier this year, T-Mobile described how the behavior of one Android IM app nearly brought their cellular data network to a breakdown in one city. Even more interesting, the US carrier describes how just the 300,000 unlocked iPhones on their network caused massive spikes in data usage. T-Mobile is using these anecdotes as evidence that mobile carriers should be able to retain control over the applications and devices on their network to ensure quality of service for all users. Do they have a point?"

Devs Grapple With 100+ Versions of Android

"The scale of the challenge facing Android developers has been laid bare by Twitter client TweetDeck. During beta testing of its new software, TweetDeck encountered more than 36,000 testers using an enormous pool of 244 different handsets. Not only was hardware for the platform fragmented, but Tweetdeck had to contend with more than a hundred different versions of Android, highlighting just how muddled the market is for the open-source platform. The splintering of Android is making life difficult for app developers. 'It's not particularly harder to develop for Android over iPhone (from a programming standpoint),' said Christopher Pabon, a developer who writes apps for both the iPhone and Android platforms. 'Except when it comes to final quality assurance and testing. Then it can be a nightmare (a manageable nightmare, mind you).'"

When You Really, Really Want to Upgrade a Tiny Notebook


"The famous Sony VAIO UX UMPC may have been cancelled a few years back by Sony, but the community at Micro PC Talk won't let it die. Modder Anh has carefully removed the relatively slow 1.33Ghz Core Solo CPU and installed a much faster Intel Core 2 Duo U7700 (a process which involves reballing the entire CPU). On top of this, he managed to install an incredibly small 4-port USB hub into the unit which allowed for the further instillation of a Huawei E172 modem for 3G data/voice/SMS, a GPS receiver, and a Pinnacle HD TV receiver. All of this was done without modifying the device's tiny external case. Great high-res pictures of the motherboard with the modded hardware can be seen through the link."
