After spending many sleepless nights I am happy to announce a new updated version ( 0.3-0 ) of Buddy is available to use now.
All details regarding the usage are available on buddy's website
http://buddy.passiongarage.co.uk , hopefully that will answer most basic questions related to usage.

Major features:

• accounts support ( link )
  budget/expense entries for a category can now be linked to an
  account ( e.g current account/credit card etc )
  
• multi currency support ( link )
  while making new entries an input currency can be chosen and
  buddy will do the conversion of the amount to the default
  currency set.
  
• wireless sync support ( link )
  now entries on the N900 can be synced wirelessly with the
  updated desktop version of buddy available for linux/windows or
  another maemo device on the same
  network.
  
• new savings report ( link )
  a new set of reports to show the usage/savings and the expense
  distribution for a selected account.
  
• snapshots ( link )
  every time a sync is done a snapshot is taken and buddy can be
  reverted back to a previous state using these snapshots.
  
• proration ( link )
  changes in how the proration works, its made simpler now for the
  user though implementing it was complicated hence this is listed
  as a major change.
• bug fixes and cosmetic enhancements.
  
• auto database migration
  The old entries and archives are automatically migrated to
  support the new features, however I recommend taking a csv file
  backup and saving it in another location prior to upgrading to the
  new version of buddy.
  
• updated linux and windows desktop versions of buddy
  ( scroll to the bottom of this link )

Minor changes:

• account/budget/expense views are now by default sorted by start date. It can be sorted by other fields by clicking the header.
• prompt while deleting entries.
• system tray messages for the windows version to reduce intrusive alerts.
• database corruption when buddy was closed while viewing archives.
• csv file changes to accommodate new fields like accounts and currencies, although the old format is also compatible.
  

NOTE:

• Please take a full backup of the database in a csv file and save it somewhere before updating, It has been tested fine but this is just in case things go wrong.
• Also take csv file backups of archive db's if its important for you.

this update was painfully long for me. I would like to be honest in saying that I did not find ample time to test this update as I would have liked to, having said that I've tested buddy for a couple of weeks and all functions seem to be working alright, but there may be issues that may come up over time which of course I shall attempt to fix.
Once everything is stable I will move it to the maemo.org download section.
