In this post i ll explain need of each application mentioned in previous post but first a point to be noted is that it is not at all important in having the most latest version of a particular app always. Older versions of the same app might be better. For example i ve seen many members requesting for latest version of smart movie and xplore in sticky thread. All having a thinking the latest version are better. Well that is true but not always as not only new features are added and bugs are edited, many processes to check unauthorised usage are also added like various authentication patches which connect to server and after some time says that the app is not legaly used and thus the whole program gets useless and also stops you installing the previous but full version like lcg xplore 1.30 after connecting to server describes your app as expired and all previous versions also dont work. To remove that error either you ve to format or you ve to install 1.05 and then install 1.22 the best version.
Moral of the story is 1.22 is not the latest version although but the best as it can be used freely by the key inputed to register and has to problem of authentication.


So starting with importance of above mentioned applications do not go for latest software always as in some cases intermediate versions have almost equal important features and on other hand can be used as full versions.

1.Power mp3
Power mp3 or winamp 2.41 is best music player for all s60v2 phones having stereo sound output. Reason is power mp3 has a preset soft rock which gives best music output for both headphones and speakers. Also one manually created preset known as super bass nokia gives music experience as of walk man series of sony (although its voice is slow and it is NOT SUITABLE FOR OLD HEADPHONES). I am giving you its link in this tutorials last post. Power mp3 is also better as it takes very less time in start up. Only drawbacks it has are if load on processor is low sound output hangs sometimes and music playback stops when some warning tone or vibration rings.
