Hi,

Yes you may loose your information..

Backup your device before upgrading...

To make a backup using your computer, you can go through iTunes. Just plug your device into your computer (or use the WiFi Sync option) and open iTunes.

Once the program is open, click the Devices button, select your device and scroll down in the summary section to Backups. There, under 'Manually Back Up and Restore,' click Back Up Now.

To make a wireless backup directly from your device, you need an iCloud account. Once you're logged in to iCloud, make sure your device is connected to a WiFi network – you can't create a backup over a cellular network. See: iCloud backup tricks for the iPhone and iPad

After you've done so, go to Settings > iCloud > Storage & Backup, turn on the iCloud Backup toggle and tap Back Up Now.

what will i lose? i backed up everything on to my computer but how would i get my "calanders", contacts and notes back on to the phone after the upgrade? how do i back up then restore text messages?

Make a backup of your device to either itunes or the cloud, and that's it.

However, I highly recommend NOT going from IOS 6 to IOS 8 on an iphone 4(s)... it will make it slower than snails piss.
