upgrading from iphone 3g to iphone 5

This is REALLY BAD advice. You don't need any 3rd party tools, and the post originally had a link to a site that sold a tool of dubious safety and quality. iTunes does this beautifully without any "help" from spammers: Transferring data from your current iPhone to a new iPhone using iTunes

As long as you backed up your old device, then no need to worry about the upgrade. All your data is under safety.

I'm in the same boat as lucky4armin, I need information regarding texts transfer from iphone 3g to the new iphone 5, I have 4 years of important texts personal and business, and I'm sure you must have found a solution by now, if not so I'm guessing I wont be able to transfer any texts from my iphone 5 to my iphone 9 If I needed to? Just doesn't make any sense. BTW text transfer did not work on itunes, just apps, contacts, notes, etc. Please help, thanks.

Here is the list of things that will be backed with iTunes:

What does iTunes back up

iTunes will back up this information:

• Camera Roll (photos, screenshots, images saved, and videos taken)
  For devices without a camera, Camera Roll is called Saved Photos.
• Contacts* and Contact Favorites (You should regularly sync your contacts to a computer or cloud service, such as iCloud.)
• Calendar accounts and subscribed calendars
• Calendar events
• Safari bookmarks, cookies, history, offline data, and currently open pages
• Autofill for webpages
• Offline web app cache/database
• Notes
• Mail accounts (mail messages aren't backed up)
• Microsoft Exchange account configurations
• Call history
• Messages (iMessage and carrier SMS or MMS pictures and videos)
• Voicemail token (This isn't the voicemail password, but it is used for validation when connecting. This is only restored to a phone with the same phone number on the SIM card)
• Voice memos
• Network settings (saved Wi-Fi hotspots, VPN settings, and network preferences)
• Keychain (includes email account passwords, Wi-Fi passwords, and passwords you enter into websites and some apps)
  If you encrypt the backup, you can transfer the keychain information to the new device. With an unencrypted backup, you can restore the keychain only to the same iOS device. If you're restoring to a new device with an unencrypted backup, you need to enter these passwords again.
• App Store app data (except the app itself, its tmp, and Caches folder)
• App settings, preferences, and data, including documents
• In-app purchases
• Game Center account
• Wallpapers
• Location service preferences for apps and websites you've allowed to use your location
• Home screen arrangement
• Installed profiles
  When you restore a backup to a different device, installed configuration profiles aren't restored (such as accounts, restrictions, or anything that can be specified through an installed profile). Any accounts or settings that aren't associated with an installed profile will be restored.
• Map bookmarks, recent searches, and the current location displayed in Maps
• Nike + iPod saved workouts and settings
• Paired Bluetooth devices (which you can only use if restored to the same phone that did the backup)
• Keyboard shortcuts and saved suggestion corrections
• Trusted hosts that have certificates that can't be verified
• Web clips
