Review: MyWi turns your iPhone into a wireless hotspot [Jailbreak Apps]

The reason that MyWi rocks (aside from the fact that it’s on the Rock store) should be pretty evident to people without a 3G modem on their laptops: it’s a jailbreak app that lets you tether and even turn your iPhone into a mobile wireless router. Not every country supports iPhone tethering, but I’m of the strong opinion that data is data and you should be able to use it on whatever device you want, and MyWi is a great little way to take advantage of every dime that goes towards your overpriced data plan.

I’m not promising that this app will prevent you from being charged for any tethering costs should you choose to use it (nobody has complained about charges on the Rock reviews), but at least it can provide an easy extra way to use your data.

How You Use It
All I had to do on my iPhone 3GS (firmware 3.1.2) was install MyWi — no extra hacks or tweaks were needed since Rock App made sure to install everything that was needed. After that all I had to do was make sure that wi-fi was activated on my iPhone, and then launch My-Wi. The app can create a hotspot over Wi-Fi or tether via Bluetooth or USB.

Data Counter
MyWi makes great use of the top bar of your iPhone and displays a pulsating tethered data counter that looks a lot like the one used for phone calls or ongoing voice memos. This is much better than Apple’s default tethering process, which requires you to go to Settings -> General -> Usage just to see how much data you’ve used overall. The data counter does tally the amounts similarly to Apple’s tethering solution, however, and so the numbers you’ll see up top are for all of your tethering, and not just the data you’ve used in one session. There doesn’t seem to be a way to reset this counter, and I haven’t used the app often enough to on the tally every month (I’ve also had some hard resets in between using MyWi, so my previous tallies were lost). If you’re really concerned about going over your data limits, I’d suggest picking up Consume from bjango on the App Store.

Tethering: Bluetooth and USB
I’ve had MyWi for a few months now and I’ve used it mainly for the wi-fi hot spot, and not for any other sort of tethering. Bluetooth always felt a bit too slow (connection and set-up wise) and USB tethering always felt too haphazard with the wiring. Most of the places I’d use MyWi at were usually lacking in desk space, and running a wire between my iPhone and MacBook just pales in comparison to simply sharing my 3G connection over wi-fi. USB tethering does have the advantage of eliminating the battery drain of sharing data, but you could also accomplish the same thing with an iPhone backup battery.
The final reason for not using either of these versions was the strange bug I encountered with regards to the data counter: it didn’t work over Bluetooth/USB tethering.

Tethering: Wi-Fi Hotspot
The wi-fi hotspot can take about 10 seconds or so to set up, but logging onto it is business as usual: find the name of the network (usually the name of your device + MyWi) and then enter the assigned WEP password. You ould also theoretically go without a password, but letting strangers onto my iPhone data plan isn’t on my list of Generous Things To Do This Year.
I used Speedtest.net to measure my download speed (5.15 Mbps) and was quite impressed — results will definitely vary based on your 3G signal strength, but speeds in downtown Toronto are pretty good.

Battery Drain
This is a tough area to measure, but I can say that the battery on my 3GS didn’t drain quite as quickly as I thought it would using MyWi as a mobile wi-fi hotspot. I once spent an hour in this mode and ran my battery down to about 60 percent, though the iPhone never got too hot to pick up and use (this was a problem with a few previous WinMo devices of mine).

Conclusion
I feel as though MyWi is an app that had to be made if only to bring balance back to the world. Sure, it isn’t free, but it does free up the data that smartphone users already pay for, and it seems absurd to have to pay extra to use my limited data plan to let me surf on my computer instead of on my iPhone.
The $9.99 asking price isn’t quite in impulse buy territory, but it’s really a small price to pay for such a fantastic utility that lets you tether and use your mobile data on your terms.

MyWi is available for $9.99 on the Rock jailbreak app store.
