First, turn on the wireless connection of your Kindle, then press “Home”, “Menu”, “Setting” and in that screen, press “311” (yap, that’s the magic number) from the Kindle keyboard. Then mysteriously, an application pops up and will warn you about this command, just select “OK”, and then you will see a message – “Scanning for available wireless providers …”.
About a minute later, a full list of network services providers (with both 2G and 3G connections) will be displayed. Just pick the one you want and that’s it !!. Try “Menu” again, and you shall see the “3G” symbol next to the signal bars, instead of previously the “GPRS“.
Please note that it does not matter whether you have a data plan with the network company to make this work, looks like Amazon already has a deal with the one listed …
Now my Kindle not only synchronize faster, it also works a lot faster when browsing the Kindle Store.
Update : If you’re using a Kindle 3 and cannot access to the numeric entry field – try pressing Alt-E, Alt-Q, Alt-Q … hope it helps.
