The very first year I visited Barcelona for Mobile World Congress, I had my phone and cash lifted from my jacket pocket. I still kick myself from time to time for the temporary lapse in attention that gave opportunists in the world’s pickpocket capital the chance to snag my stuff.Of course, I was aware of the local pickpockets’ reputation. And all week, I’d been careful. I kept a watchful eye out. And all week, I’d held onto my belongings. But on the last day, at 5:30 in the morning, in front of the airport, I let my guard down. I paid the cabbie and absent-mindedly shoved my phone and unspent cash – maybe 30 Euros – into the side pocket of my coat. And by the time I got to the airline counter, they were gone.If you haven’t been to Barcelona, don’t let the story dissuade you. It’s a great city. And it hasn’t happened again since. Really, it’s not that difficult to hold onto your stuff. You just need to pay attention when … [Read more...] about Faster, more reliable networks in your future

Personal Hotspot was introduced many years ago as a way to turn your iPhone (and later iPad) into a conduit between a cellular data connection and one or more computers or other devices. Macworld reader Gabriel was hoping to use Personal Hotspot after his MacBook Air’s internal Wi-Fi system apparently conked out.Gabriel is in ultima Thule, far from cellular networks, but has access to a Wi-Fi network. He tried to use Personal Hotspot to tether his Mac via Bluetooth and USB to the local Wi-Fi network, but couldn’t get it to work. “Every time I try to pair the two, the Wi-Fi connection drops off on the iPhone,” he writes.That’s by design. Apple doesn’t have a way to use Personal Hotspot with Wi-Fi networks, even when you’re tethering through USB or Bluetooth, leaving Wi-Fi available. With Personal Hotspot turned on, any active tethering disables the Wi-Fi connection, and relies entirely on the cellular one. (It has been possible to relay Wi-Fi … [Read more...] about Can an iPhone’s Personal Hotspot feature connect to a Wi-Fi network?
