Very quick iPhone application fix

Hi We have a completed iPhone app which runs perfectly fine on the emulator. However, there is a certain feature in the app which crashes the app when it is run on the device (iPhone/iPod touch). The feature gets data from a webservice and stores it in the database. Pls note, this feature runs perfectly fine on the emulator, only causes an issue on the device. For an experienced programmer it is a matter of only a few mins to sort this out. We are looking to spend 15-20 USD for this quick job. You should have the device (iPhone/iPod touch) with OS 3.0 or higher as well as emulator to study the crash report/log. We need this URGENTLY and pls bid ONLY if you can complete in a couple of hours. Happy Bidding
