How to download apps without a wireless data plan I bought an i7500, no data plan. I had assumed that connecting to my router would allow me to download apps from the marketplace; apparently not. I get a message about not being able to connect via the SIM data plan.

Is there a way for me to download and install apps without actually getting a data plan?
xda developers has a guide for this. See Guide: Using Android Without a Data Plan. I cannot verify these instructions but the comments in the xda thread seem positive.

Below is the section regarding getting apps: 


  The easiest way to find apps is to type the app name and apk into
  google, but most of the time, this does not work (and is illegal for
  paid apps, unless you get it from the dev directly). Since this
  doesn't usually work, you can get apps using a special avd and the
  android emulator.
  
  
  Download/Setup the Android SDK and Download the accessmarket.rar file (originally found at
  http://tech-droid.blogspot.com/2009/...-emulator.html)
  Copy the contents of accessmarket.rar to C:/Users//.android/avd/ - you might have to enable "show hidden files"
  in folder options to see the .android folder
  Edit C:/Users//.android/avd/AndEmu.ini, and change the username in the file to your username
  Start SDKSetup.exe, then click Virtual Devices, launch the device called "AndEmu"
  Once this is started, download ASTRO file manager from market (it works in this emulator!) - ASTRO will allow you to backup the apks for
  apps that you download from the market. (NOTE: for protected/private
  apps, you can use Titanium Backup to back them up)
  
  5.5. You can download any app from the market, and back it up
  The apps you backup will be backed up to /sdcard/backups/apps/
  You can use one of the following adb commands to pull these files from the emulator:
  
  adb pull /sdcard/backups/apps/ /AndApps
  
  This will download all of your backed up apps to a folder on your
  root drive called AndApps
  
  or
  
  adb pull /sdcard/backups/apps/.apk /AndApps/.apk
  
  This will copy a single apk of your choosing to /AndApps/
  After you do this, you need to copy the apk to your sdcard (either by taking the card out, or using the SD Share widget), and then you
  can install it to your phone with ASTRO
  
  
  Note: Special Applications:
  
  Some applications like to let you download themes and such within the
  app, without any other source. Most of these applications store files
  on a folder named after the app (com.something.something) so you can
  download the stuff within the app on the emulator, and backup the
  folder on the emu's sd card and put it on your phone.
