Ganz tolle Suche. Wie soll eine Datenbank auch einschränken, wenn keine Einschränkungen eingetragen sind?

Im Android Sektor aussichtslos. Alternative: Kamera ausbauen.

Ich kann mich nur wiederholen, der Market funktioniert bei mir. Push Mail nutze ich (momentan) nicht (mehr).

Also ich kann mich gar nicht beschweren...Freitag, Sonntag und heute Apps ohne Probleme geladen. Gerät ist ein mittlerweile freies Desire mit Android 2.2.

Ist doch eins drauf :confused:

Mir ist es wurscht, was bei Apple abgeht. Wir sind hier im HTC Bereich, richtig?
-
Ja, jedes Vertragsgerät hat KEINEN lock. Wie oft muss das hier eigentlich noch gesagt werden?
-
Wahrscheinlich hat BildMobil das Tethering einfach gesperrt.

Aided GPSIn an effort to drop the TTFF in general and particularly in poor visibility conditions, companies like Sirf and the privately owned Global Locate introduced mechanisms to help receivers in obtaining ephemeris data without the need for the usual wait associated with it.
Notice that there is a difference between Assisted and Aided GPS (both called AGPS to complicate things a bit). Aided GPS is "generally understood to be either ephemeris or almanac aiding". While Assisted GPS uses data from a wireless network infrastructure, sometimes down to location information itself based on the Cell ID from a mobile phone.
There is also a difference regarding where changes are made to provide this aid: at the control plane by modifying TCP/IP format within the actual wireless network infrastructure or at the user plane where no major upgrades are necessary and the distribution is made thru messages like SMS for example.
Global Locate uses Trimble survey grade reference receivers to build its own private reference network to "collect, format and redistribute live ephemeris". This data is then used to provide Long-Term Orbit (LTO) data based in orbit models that according to this PDF will provide very precise satellite ephemeris good for up to 10 days.
The HP 6500 PDA includes "Quick GPS Connection" software that makes use of Global Locate LTO data which can be obtained thru a cradle sync or downloaded from the Net. GpsPassion tested it against a SirfStarIII equiped receiver.
Motorola phones equipped with GPS receivers already make use of Sirf's SirfLoc servers through its iDEN (Integrated Digital Enhanced Network) to obtain aided information for fast fixes.
Sirf just announced InstantFix, a mechanism similar to that provided by Global Locate where users will be able to download ephemeris good for up to 7 days for use with their receivers. In the same week that Sirf announced this service, GlobalLocate announced two patents just obtained covering the generation and distribution of LTO data. Let's hope they figure out a way to work together.
One of the selling points from LTO vendors is that knowing "where to look" for a signal a GPS receiver can use a lot less power to keep track of its location, from very weak signals and even under very poor visibility conditions, including indoors.
GpsPassion has a comparison of the Cold Start and Hot Start times for several GPS receivers for PocketPC's. For more info on Global Locate check this article from GPSWorld.

Wie ich darauf gekommen bin: Ich habe bei google Aided GPS eingegeben -
Ist ja schön und gut, aber hast du schonmal nen 23'' Notebook gesehen?
