Help Should I downgrade or upgrade firmware? and what to?

Hi,

My wife and I both got a Samsung Galaxy S1 from Telstra about 5 months ago and we haven't been happy with the lag and slowness of general navigating through the phone i.e bringing up contacts, a website, loading of apps etc and have gone so far as to tell friends/family to stay away from these phones simply out of frustration.

One friend looked at my phone and saw the following information

Model N

Are these phones network locked ? I have GT-I9000 and using XXJVK Gingerbread and I am happy.

If network locked, you could apply lagfix but I think you will void your warranty. There is no downgrade for Galaxy phones but upgrades are there. Telstra can help for an upgrade.

If phone is not locked to Telstra, you have plenty of choices to install newer ROMs.

Downgrading Eclair (code name of version 2.1)? Hardly, I would recommend to upgrade .... at least to Froyo (code name of 2.2) or Gingerbread (2.3).

Using Kies (Samsung's official upgrade tool) you should be able to upgrade at least to 2.3.3. The most recent version is 2.3.5 and is available at http://www.samfirmware.com/apps/blog/show/8512833-android-2-3-5-for-galaxy-s- but its not official yet (means you would have to "root" your phone).

You don't need to root your phone to install any stock (leaked or official) ROM.
