Posted by Markus Birth on
iPhone Android (esp. Nexus One)
It's from Apple. It's NOT from Apple. (or: It's from Google.)

~150.000 Apps (most are gimmicks though) ~30.000 Apps and growing, some well-known web-based services still missing as a native App
Apple decides which apps get onto the phone/in the AppStore very loose controlled Market store

supports Push Notifications via Apple servers Push Notifications are a bit complicated and not native (e.g. IBM MQTT) but can use Jabber/XMPP messages via Google Talk for notifications
Tethering depends on network carrier / paid Tethering via different methods from free to $30
cheap iPhone OS upgrades in the future (OS2 → OS3 for iPod Touch was $9.95), new versions still support (almost) all old devices Android updates depend on cell phone maker

iOS and Crashing Applications

Posted by Markus Birth on

If you have to problem that some apps crash directly after running them, i.e. you see the app "popup" but it immediately disappears leaving you back at the home screen, it might be a problem with Apple's DRM. This can occur if a Sync with iTunes is aborted or the connection was lost.

Navigation for iOS

Posted by Markus Birth on

xGPS

(You need a jailbroken iPhone for this.)

xGPS is a navigation system which uses Google Maps for routing and display of the map. It can download map tiles for offline use and can use the "normal" map as well as the terrain map of Google Maps. Your current position is shown centered together with your route and you'll get turn-by-turn directions from a synthetic voice. It can recalculate the route if you get off it.

Apple iPhone SSH Access

Posted by Markus Birth on

You need a jailbroken iPhone for this.

  1. use Cydia to install the OpenSSH package
  2. enable WLAN access and find your iPhone's IP (see Settings → Wi-Fi → \ → IP Address)
  3. under Linux type: ssh <IP address> -l root; for Windows use PuTTY
  4. (the first connection will need about 20-30 seconds1 before you'll be asked to accept the host key)
  5. use the following password: alpine (older iPhones used dotty)

  1. most probably the iPhone will generate some encryption keys here ↩︎
