yahoo installation

[iMore Question]

Dear Sir
I bought one i5s recently but unable to check yahoo mail in it & saying unable to connect server or IMAP Id or password is wrong.But G mail or mail ru is installed successfully.Number of times I ve asked many people & even showroom person but they are unable to guide. I am really worried.
Please guide me.
Secodly is it all the times i have to purchase the application from apple for the use of it unlike samsung gives it free in android which is easy to operate.
I want to install a dictionary for the need.
sincerely
Jagannath Bal

For the dictionary, just search in the App Store. I have the Dictionary.com application, which is free, and I am sure there are many more in the App Store. For your Yahoo, are you able to log in on your PC or other device?
