I will NOT give you a recommendation.  Why?

1.  I don't know your network; and

2.  I don't want to be responsible for any issues in the future after you run the new IOS.

Read through each of the Release Notes of the version you choose and make the decision from there.

Sorry, this question is a tad bit "iffy".  What do you mean by this?

Do you have a valid Cisco Service Contract to download IOS from the Cisco website?

Ok yesterday I was panicking,

I wana learn more about upgrading an IOS, not just only looking for Flash and DRAM memory before I choose the IOS.

• •1.       What else can I look for before I choose the IOS?
  
• •2.       What’s the difference between M, T, etc.… ?
  • •a.       c3845-advipservicesk9-mz.12.4-24.T1
    
  • •b.      c3845-advipservicesk9-mz.15.0-1.M6
    
  • •3.       I thought the latest IOS comes with better and more functionality I can use, like just upgrading from Windows XP to Windows 7 as long as my Machine supports that.
    

I tried to download the IOS, but it seems like I don’t have Cisco Service Contract to download IOS from the Cisco website.
